Wall and Ceiling Mount A/Vs
Description
Multi-Candela TrueAlert A/Vs with horn and
synchronized strobe provide convenient installation
to standard electrical boxes. The enclosure designs are
both impact and vandal resistant and provide a convenient
strobe intensity selection. Since each model can be
selected for strobe intensity output, on-site model
inventory is minimized and changes encountered during
construction can be easily accommodated.
Wall mount A/V housings are a one-piece assembly
(including lens) that mounts to a single or double gang, or
4” square standard electrical box. The cover can be
quickly removed (a tool is required) and covers are
available separately for color conversion.
Ceiling mount A/Vs install using standard 4” electrical
boxes. Color choice is determined by model number.
Strobe Intensity Selection
During installation, a selection plug at the back of the
housing determines the desired strobe intensity. An
attached flag with black letters on a highly visible yellow
background allows the selected intensity to be seen at the
side of the strobe lens.

Strobe Application Selection
SmartSync Two-Wire Control
Proper selection of visible notification is dependent on
occupancy, location, local codes, and proper applications
of: the National Fire Alarm Code (NFPA 72), ANSI
A117.1; the appropriate model building code: BOCA,
ICBO, or SBCCI; and the application guidelines of the
Americans with Disabilities Act (ADA).
SmartSync operation mode allows a two-wire circuit to
provide the ability to activate both the horn and strobe on
the same NAC and then allow the horn to be silenced
while the strobe remains flashing. The horn operates as
“on-until-silenced” while the strobe operation is
“on-until-reset.”
Synchronized Strobes
SmartSync Control Sources
Multiple Strobes. When multiple strobes and their
reflections can be seen from one location, synchronized
flashes reduce the probability of photo-sensitive reactions
as well as the annoyance and possible distraction of
random flashing. The multi-candela strobes of these A/Vs
are synchronized by the controlling SmartSync operation
NAC.

• SmartSync Control Module (SCM) 4905-9938 (refer to

NOTES:
1. “Regulated 24 DC” refers to the voltage range of 16 to 33 VDC per UL Standard 1971, Signaling Devices for the Hearing Impaired,
changes effective May 1, 2004. This voltage range is the absolute operating range. Operation outside of this range may cause
permanent damage to the appliance. Please note that 16 VDC is the lowest operating voltage that is allowed at the last appliance on the
NAC under worst case conditions.
2. Coded values are typical of the output measured with a Temporal coded or a March Time coded pulse and with a sound level meter
reading on a “fast” setting. Polar dispersion per ULC S525 testing = -3 dBA at +/-40° off-axis; -6 dBA at +/- 50° off-axis.
3. Currents are with horn on steady. The maximum RMS current listed is the device nameplate rating. Strobe designs are constant wattage
and the maximum RMS current rating occurs at the lowest allowable operating voltage. (RMS is root mean square and refers to the
effective value of a varying current waveform.)
